Default Re: 478 to SM420

I guess nothing is simple. I would assume an engine building machine shop could balance the 478, also assume the whole engine would need to be disassembled and each part weighed. I will need to check with my local machine shop to see if they can handle it.

I think that even I had the 379 balancer to go with the flywheel it would still need to balanced given the piston weight difference of the larger 478 piston.

Next stop machine shop to see if they can handle this.

Thank you.
